Sixteen-foot bay doors open up into Denver Automotive and Diesel Center's 18,000-square-foot facility, a space where techs get cars, diesel trucks, and RVs in working order. And while visits primarily concern services such as oil changes, tune ups, and alignments, that might not be the only reason you pop in. WiFi permeates an eco-friendly waiting area, with a kids' center, five televisions, a chalkboard wall, and drinks and snacks. While they wait, guests rest easy knowing all parts and labor is covered by a two-year warranty, and that the business offers a local shuttle service should they need to get away.

Cars are made to travel. But after a long trip overseas and miles of maneuvering American roads, import vehicles still require their own brand of service. That's where Automotive Specialists comes in. Specializing in Japanese imports, the shop's ASE-certified technicians reboot cars by repairing transmissions, alternators, and electrical systems. Maintenance services such as oil changes and tire rotations breathe new life into vehicles that have been slowed down by sluggish engines or ticklish tire treads.
Although the facility specializes in imports, its technicians' extensive training breeds a familiarity with all makes and models. Automotive Specialists also partners with Enterprise Rent-A-Car so that customers can commandeer a new set of wheels while their cars are being treated.

Dennis Cooper started repairing cars from a simple one-door garage with two bays. Over the last 30 years, his needs have steadily grown, as his robust business repeatedly outgrew four- and six-bay facilities. He and his team of ASE-certified technicians now stretch their legs through eight service bays, with Dennis's wife, Kathy, keeping watching over the books. Experienced technicians—including two ASE master mechanics—perform maintenance and diagnostic services on every part of vehicles and frequently add to their knowledge with seminars and schooling.
The center boasts a Hoffman wheel alignment system, which uses a Windows operating system and multiple laser beams to ensure accurate alignment, as well as two oversized shop bays to accommodate larger and diesel vehicles. The Cooper's Automotive team can also soup up performance with off-road lift systems or give vehicles a distinctive look with a custom fixtures and chrome tips. Recognized for excellence in emissions repair, the shop also recently installed solar panels on its roof to produce electricity and reduce its carbon footprint.
